Arteries
The arteries are an important and important part of the circulatory system within the body. Its mission is to transfer blood from the heart to all the organs of the body to feed it. Coronary arteries are important and unique from other arteries because it transfers blood to the heart muscle itself to carry out its tasks and functions And the coronary artery may be exposed to diseases that weaken it as a result of the unhealthy life system. In this article we will introduce you to the location, dissection, and flow of the coronary artery.
Coronary artery location
The coronary arteries are divided into two main parts, which branch out from the aorta, or aortic artery, and is one of the largest arteries in the body. Its mission is to transfer blood from the heart to the rest of the body. The right coronary artery transfers blood to the right atrium, while the coronary artery Left blood to the left atrium.
Coronary artery dissection
The coronary arteries are divided into two main arteries: the left coronary artery, the right coronary artery, and the presence of another artery called the posterior coronary artery. All these arteries begin since the aortic root starts directly above the aortic valve, While the right artery is emitted from the right aortic sinus.
It should be noted that the posterior coronary artery can only be found in 4% of the population. There are rare cases where you have only one coronary artery around the beginning of the aorta, and there are cases of double coronary artery, for example you may find two coronary arteries parallel to each other While the normal thing is that there is only one artery on each side.
Coronary artery flow
When the ventricular heart muscle contractes due to high pressure in the ventricle, pressure is placed on the coronary vessels that enter the heart muscle. However, the external coronary vessels, ie vessels located on the outside of the heart, remain as they are. In this case, the blood flow stops below the heart muscle Causes most blood flow during the process of relaxation of the heart, ie when the coronary vessels remain under the heart as they are, and are low pressure, which leads to difficulty in filling the coronary arteries, and lead to the difficulty of delivery of oxygen due to lack of blood flow to the heart to tissue injury Makkemia, It is a boundary O Lack of oxygen, and Axima causes acute pain in the chest called angina.
